AbstractAgricultural production is an important source of ground water contamination in many regions of the U.S. Ground water contamination is the unintended side effect of actions by economic agents pursuing their interests within the legal framework established by current public policy. Under existing policy, agricultural producers do not have changes as noted to consider off-site effects of their decisions on ground water supplies. Given these policy rules, producers can be expected to cause such damage until their rights and obligations are adjusted by policy. The farmer is simply responding in a predictable manner to opportunities existing within the economic system. Possible rationales for government action to protect ground water quality include: 1) the existence of “third party” effects in the form of off-site damages associated with degraded water supplies; 2) overuse of an “open-access” resource; 3) society's desire to make conservative ground water management decisions to avoid the risks of contamination; and 4) individuals' demands for ground water protection even though they may not expect to directly benefit. Alternative policy instruments for ground water protection include taxes, subsidies, regulations and prohibitions, education, and public spending. Different policy approaches are being employed to address agricultural contamination of ground water. One policy approach emphasizes producers ' lack of accurate information and appropriate decision-making, and recommends educating farmers about how their profits can be increased by improved decisions regarding inputs. A second approach is to change the rules and incentives to compel or induce producers to act in a way that improves ground water quality. If ground water quality follows the pattern of most public issues, effective policies will be developed only as the cost of failing to act becomes known. Research and delivery of information on the costs of ground water protection and the costs of not protecting ground water are likely to be key factors affecting the formation of future ground water quality policies.

AbstractContamination of ground water from agricultural sources has been documented in a majority of the contiguous United States. In this study, we examine the potential for voluntary adoption of management practices that reduce risk of ground water contamination and discuss how f arm operators' attitudes regarding the environment might affect the success of voluntary programs. Farmers' behavior and attitudes in Rockingham County, Virginia, and Big Spring Basin, Iowa, reveal that both groups consider the ground water issue to be a serious problem to which they are contributing. This awareness is a significant first step in prompting consideration of management practices that reduce the threat to ground water quality. We also found that the “worst offenders”—that is, farmers applying nitrogen well above agronomic recommendations-were those with the least concern about the problem. If major shifts in farming practices are to occur voluntarily, major incentives or disincentives are needed. Even though the concern about ground water quality is high, the documented risks perceived by farmers are not strongly convincing. The economic incentives for change are questionable at best. Voluntary adoption of best management practices is only one of several policy options. Ultimately, policies designed to reduce ground water contamination may need a mix of strategies, including economic incentives and disincentives, zoning and land use restrictions, environmental regulations, and bans on agricultural chemicals.
